It is used to find out the centroid, incenter and excenters of a triangle.In physics, it is used to find the center of mass of systems, equilibrium points, etc. Suppose that P(x 1, y 1) and Q(x 2, y 2) are two points and let M(x, y) be the midpoint. AB-= |(-4) - 2| 2= |- 6| = 6-5-4-3-2-1 0123 AB Find the distance between A(-2, -1) and B(1, 3). 3. Solved examples on the Section Formula in coordinate geometry. Evaluate the value of λ i.e., the ratio. 4. A coordinate graph consists of a rectangular grid with two crossing lines called axes. Here, we have provided some advanced calculators which will be helpful to solve math problems on coordinate geometry. The distance of a point from the y-axis is called its; x-coordinate, or abscissa. Apply the coordinates of the given three points in the area of triangle formula. Hence the x‑coordinate of M is the average of 1 and 5. x = 5 + 1 2 = 3 The y coordinate of M is the average of 2 and 8. x = 2 + 8 2 = 5 Thus the coordinates of the midpoint M are (3, 5). Distance between Two Points y x’ y’ x PART-1 2 . The determination of the coordinates of any figure, plane or any point in space and application of the various geometries on these figures is called as Coordinate Geometry. Proof: Let O be the origin and let OX and OY be the X-axis and Y-axis respectively. While solving a coordinate proof for any shape, you first need to know the properties and the definition of the shape.
